The first picture looks like an after-the-fact fix. Originally there was no seal in the engine, just an oil slinger. Someone put in an oring and then glued a seal. Kits have been available in the aftermarket for years. The right most nick circled I would not worry about but the other nick in the original slinger might be an issue. Behind the oring should be a snapring holding it in. That needs to come out and then in theory the slinger can come out. Admittedly this is easier done with the engine dismantled.

Somebody tried to use a roller bearing for the sprocket spacer, and then thought the O-ring and 'goober' would seal against oil, probably for a belt-drive.
If a belt-drive is installed, the shouldered thrust washer pressed into the main bearing housing must be replaced with a modern hybrid with a seal.
If you have a chain-drive, you only need the proper sprocket spacer.

I must ask again: Is there a chain primary drive provided, or is it an after-market belt-drive assembly?
The original chain drive is easiest, by far.
